Geomicrobiologists have been exploring the ground under our feet – looking at rocks and strata that go back even earlier than the Jurassic. Bacteria are still living in them. Deep life has been found all over the world under a variety of conditions. In oil fields, coal mines and gold mines, beneath the ice sheets that cover the Antarctic and Greenland – virtually everywhere. They are especially common in sediments on the ocean floor.
The research findings, it is hoped, will help space scientists to seek out life on Mars and the moons of Jupiter and Saturn.
